Health-related quality of life among persons living in Japan with a permanent colostomy.

OBJECTIVE: To compare the health-related quality of life (HRQOL) of persons with a permanent colostomy to that of the general Japanese population and explore the factors influencing HRQOL. DESIGN: A cross-sectional survey. SETTING AND SUBJECTS: A total of 255 persons with an ostomy who attended a meeting of the Japan Ostomy Association in the Kanto region of Japan. INSTRUMENTS: The HRQOL was assessed using Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36), Japanese version 1.2. Factors potentially influencing the HRQOL were age, sex, marital status, employment status, number of people in the household, time since colostomy, and diagnosis. METHODS: Questionnaires were distributed to the subjects and SF-36 scores were determined and compared with the corresponding national-norm data by Wilcoxon signed rank sum test. A logistic regression analysis was used to explore the influencing factors. RESULTS: The questionnaire response rate was 66.7%. Subjects with a urostomy or an ileostomy and those with missing data were excluded. Data from 102 subjects with a permanent colostomy were analyzed. The subjects' scores were significantly lower than the national-norm scores in the role-physical and social functioning scales. Being employed was associated with significantly lower scores or associated with a tendency toward lower scores. CONCLUSIONS: Scores in two scales in these subjects were lower than those of national-norm scores. Being employed had a negative impact on the HRQOL of subjects with a permanent colostomy. The results of this study provide reference data for future research and underscore the importance of support for persons with a colostomy.
